Alstroemeria plant named ‘Koncavanti’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named ‘Koncavanti’, characterized by its compact and mounding plant habit; sturdy and strong plants; vigorous growth habit; pink-colored flowers with distinct dark purple-colored stripes; and good garden performance.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘KONCAVANTI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, typically grown as a potted garden Alstroemeria, and hereinafter referred to by the name ‘Koncavanti’.

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventor in Nieuwveen, The Netherlands. The objective of the breeding program is to create new compact potted garden Alstroemeria plants that are early and freely flowering and have attractive leaf and flower coloration.

The new Alstroemeria plant originated from a cross-pollination made by the Inventor in Nieuwveen, The Netherlands on Apr. 22, 2004 of a proprietary Alstroemeria hybrida selection identified as code number 5261-4, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as code number 7567-3, not patented, as the male, or pollen, parent. The new Alstroemeria plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Nieuwveen, The Netherlands on Aug. 24, 2005.

Asexual reproduction of the new Alstroemeria plant by root divisions in a controlled greenhouse environment in Nieuwveen, The Netherlands since Oct. 31, 2007, has shown that the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Koncavanti’. These characteristics in combination distinguish ‘Koncavanti’ as a new and distinct cultivar of Alstroemeria plant:

-   -   1. Compact and mounding plant habit.     -   2. Sturdy and strong plants.     -   3. Vigorous growth habit.     -   4. Pink-colored flowers with distinct dark purple-colored         stripes.     -   5. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the female parent selection. Plants of the new Alstroemeria differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Alstroemeria are more compact than plants         of the female parent selection.     -   2. Plants of the new Alstroemeria and the female parent         selection differ in flower color as plants of the female parent         selection have red-colored flowers.

Plants of the new Alstroemeria can be compared to plants of the male parent selection. Plants of the new Alstroemeria differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Alstroemeria are more compact than plants         of the male parent selection.     -   2. Plants of the new Alstroemeria and the male parent selection         differ in flower color as plants of the male parent selection         have red-colored flowers.

Plants of the new Alstroemeria can be compared to plants of the Alstroemeria hybrida ‘Konpride’, disclosed in U.S. Plant Pat. No. 20,050. In side-by-side comparisons conducted in Nieuwveen, The Netherlands, plants of the new Alstroemeria differed from plants of ‘Konpride’ in the following characteristics:

-   -   1. Plants of the new Alstroemeria were broader than plants of         ‘Konpride’.     -   2. Plants of the new Alstroemeria had longer leaves than plants         of ‘Konpride’.     -   3. Flowers of plants of the new Alstroemeria were larger than         flowers of plants of ‘Konpride’.     -   4. Flowers of plants of the new Alstroemeria had longer perianth         segments than flowers of plants of ‘Konpride’.     -   5. Plants of the new Alstroemeria and ‘Konpride’ differed in         flower color as plants of ‘Konpride’ had bright pink-colored         flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Alstroemeria grown during the summer in 19-cm containers in Nieuwveen, The Netherlands and under conditions and practices typical of commercial potted Alstroemeria production. For the first 16 weeks after planting, plants were grown in a glass-covered greenhouse and during the last 20 weeks of production plants were grown in an outdoor nursery. During the production of the plants, day temperatures ranged from 6° C. to 30° C. and night temperatures ranged from 6° C. to 16° C. Plants were 36 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
